gem install pg --with-pg-config 有效，捆绑失败 [英] gem install pg --with-pg-config works, bundle fails

问题描述

当我运行时(以 root 身份)

WhenI run (as root)

gem install pg -v '0.12.0' -- --with-pg-config=/usr/pgsql-9.1/bin/pg_config

我得到以下输出:

#-> gem instal pg -v '0.12.0' -- --with-pg-config=/usr/pgsql-9.1/bin/pg_config
Building native extensions.  This could take a while...
Successfully installed pg-0.12.0
1 gem installed
Installing ri documentation for pg-0.12.0...
Installing RDoc documentation for pg-0.12.0...
#-> 

当我运行捆绑安装时:

An error occured while installing pg (0.12.0), and Bundler cannot continue.
Make sure that `gem install pg -v '0.12.0'` succeeds before bundling.

我在/usr/pgsql-9.1/include/libpq-fe.h 中安装了 libpq-fe.h.所以，我尝试了

I have libpq-fe.h installed at /usr/pgsql-9.1/include/libpq-fe.h. So, I tried

gem install pg -v '0.12.0' -- --with-pg-config=/usr/pgsql-9.1/bin/pg_config --with-pg-lib=/usr/pgsql-9.1/include/libpq-fe.h but still no go. 

任何帮助将不胜感激.

另外，我已经安装了 postgresql91-devel 和 ruby​​-devel.运行 CentOS 6.

Also, I have installed postgresql91-devel and ruby-devel. Running CentOS 6.

推荐答案

在运行 bundle install 之前你试过运行这个吗?

Have you tried running this before running bundle install?

bundle config build.pg --with-pg-config=/usr/pgsql-9.1/bin/pg_config
